I found a very cool website that lets you load a completely different theme into your browsers' home page.

very nice, I thought when I came across it. So I decided to change my browser's home page with a different look and theme.

check it out:

Recent Google Themes : PageRock
just click on the page that you like, load it up into your browser's HOME icon at the top of your browser and your set.
Simple and cool, eh??
